WRITER FOR TIRE PRESSURE SENSOR

摘要

A writer for a tire pressure sensor is disclosed, which is adapted to hold the tire pressure sensor to write a program to the tire pressure sensor. The tire pressure sensor has a first connection port. The writer includes a housing, a positioning member, and an ejection device. A surface of the housing forms a receiving recess, and a second connection port is provided in the receiving recess. When the tire pressure sensor is received in the receiving recess, the first connection port thereof is connected to the second connection port. The positioning member connected to the housing has a block section abutting against the tire pressure sensor to keep the first connection port being connected to the second connection port. The ejection device is adapted to exert a pushing force on the tire pressure sensor to eject it for separating the second connection port from the first connection port.

主权项

1. A writer for a tire pressure sensor, wherein the writer is adapted to hold the tire pressure sensor to write a program to the tire pressure sensor; the tire pressure sensor has a first connection port; comprising:
a housing, which has a receiving recess and a second connection port, wherein the receiving recess is recessed into a surface of the housing, and the second connection port is provided on a bottom of the receiving recess; when the tire pressure sensor is received in the receiving recess, the first connection port of the tire pressure sensor is connected to the second connection port; a positioning member, which is connected to the housing, and has a block section, wherein a top surface of the block section is an outward curved surface; the positioning member is pivotable between a first position and a second position; when the tire pressure sensor is received in the receiving recess and the positioning member is located in the first position, the block section of the positioning member abuts against the tire pressure sensor, whereby the tire pressure sensor stays inside of the receiving recess; when the positioning member is located in the second position, the block section of the positioning member leaves the tire pressure sensor; and an ejection device, which is adapted to exert a pushing force on the tire pressure sensor, wherein, when the tire pressure sensor is received in the receiving recess and the positioning member is located in the second position, the ejection device ejects the tire pressure sensor to separate the second connection port from the first connection port; wherein the housing has a barrier protruding from a top edge of a sidewall of the receiving recess toward the positioning member; when the tire pressure sensor is received in the receiving recess, the tire pressure sensor abuts against a bottom edge of the barrier; wherein the housing has a pit communicating with the receiving recess; the positioning member has two opposite ends, wherein the block section is at one of the ends, and is hook-shaped, while the other one of the ends is pivotally connected to the housing, so that the positioning member is pivotable between the first position and the second position in the pit.
